Yes, solar panels can be installed on research facilities or laboratories. In fact, many research facilities and laboratories have started to adopt solar energy to reduce their carbon footprint and dependence on traditional energy sources. Solar panels can be installed on rooftops or open spaces adjacent to the facility, providing clean and sustainable energy to power various equipment and operations. Additionally, the installation of solar panels on research facilities can serve as a demonstration of renewable energy technologies and encourage further adoption within the scientific community.
Yes, solar panels can be installed on historic homes or buildings. However, it is important to consider the specific regulations and guidelines set by local historic preservation boards or authorities. In many cases, there are alternative installation methods available that minimize any visual impact on the historic aesthetics of the building. It is advisable to consult with experts in historic preservation and solar installation to ensure compliance with any necessary requirements.
I want to install a solar panel system and our power grid can't work in reverse(so it get its electricity from us). My question is how do you prevent electricity from our panel to go to the grid without disconnecting the grid? How can we also use the grid and the panel at the same time when the panel are not creating enough power?PS dont say ask an electrician
If you are grid-tied, then a standard solar electric system will always feed back into the grid if you are not utilizing more power in your home than is being generated by the solar panels and inverter system. It is possible that a grid isolation device designed to prevent direct back feeding is available, but haven't heard of one in common use. New laws in most areas of the US are now mandating that utilities allow grid-tied alternative energy systems. Double-check you local laws. Sometimes you can't take the utilities word for truth--most will automatically say 'no' and will only relent when you show up with the law in hand. Unfortunately, some utilities have figured out another way to shut down alternative energy pioneers--they demand multimillion dollar insurance policies covering damage that their equipment could sustain from your little PV system. Technically, they are still in compliance with the law, they just make it impossible for a homeowner to meet their requirements. If you are getting the runaround, go to your state representative for help. It's amazing how contrite those utility people can be when a state senator (or even US Senator) has just sent a letter asking them why they are stonewalling a law-abiding and well-meaning citizen. Good luck, and don't give up!
how to use a motor with solar panel
A solar panel cannot operate a motor by itself. A typical system operates like this: The solar panel is connected to a charge controller which is connected to a battery which is connected to a motor controller which is connected to the motor. All these components must be compatible with each other. So,in other words, you can't run just any old motor with a solar panel.You can buy a system like an electric gate opener which is solar powered.
This is the cenario. Your yearly energy use comes by mail and it states that the total amount of energy used your household is 7000kWh.Then you make the decision of switching to get solar panels. The question is what area should your solar panel be given that the average annual length of daylight is 2.0.
It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
I bought a pack of OEM mini solar panels that produce 4.2v and 22mA and I was just wondering how many LED's I could hook up to one mini solar panel? I currently have one green LED with a resistor on the one panel but was wondering how many I could possibly run off of one panel?
You need to answer that by designing circuits to provide each LED with its specific voltage and current requirements, and then see how many you can supply.
how long till a 50 watt solar panel pays itself off in buffalo, ny if its $500. i have national grid and heres the link to the rates. i am residential.
I have a small system and do not make enough to sell back (no batteries) so it was less than 7 years BUT when you are talking about putting the initial in to a high yield div account and comparing it then I would say it took only 4 years to pay for because I was invested like many others with the capital it would have taken to get a large system and that investment LOST money while my solar pays for itself every year bit by bit. With systems now more efficient and rebates bigger and the investment alternatives not any better it is an easy choice.
who has solar panels on their home and are they worth it
They're only worth it if: # - you are rich enough to afford them over the long term. Commercially installed solar panels will take you over 0 years to see any financial benefit. #2 - you get the parts and some instructions and get them built yourself. DIY or get a local electrician to put them together. If you don't fit into any of these 2 categories, then they're NOT worth it.
